4130 & 4140

[G.T.]

Hi Rich, Thanks for the input! I don't think steels like we have now were readily available in 1900 thru WW1??... Trigger bars, hold opens, trigger levers, firing pins, ejectors and the like show some heat treat...toggles, and breech block some heat treat as well.. and I realize 1018 isn't a candidate for those applications.. but 1050 certainly would be.. And, if they had 1095, I would think, it'd just be by accident, as the processes for tempering & drawing that material wasn't known back then... I'd say 1075 max... and I'll stick to my guns on the 1018 until some one can prove different??? ... I can remember Winchester with chrome-moly steel in the barrels back in the 30's and such, and they didn't hold blue worth a crap?? ... If Sam Bucemi is still checking out the forum, I'd certainly like his opinion... Maybe our European guys will know??... ... best to all, til...lat'r....GT...
